Yeah, weird that this isn't the new e-stat. From the outside it looks identical to it.

I was also told by HiFiMan that the stat + 300B amp is in the works.

God it's ugly. I wish it was still in prototype stage.

I do not see any evidence of a single sided planar.
What I do see in that Chinese presentation is a 'symmetric' driver with very small size magnets (probably power full !) on the 'ear side' and bigger magnets on the oustide.
This would have lower distortion than a single sided planar, have a quite similar wavefront and have the approx. weight of single sided drivers as a bonus.
Seems like a good idea.

Maybe next year they will invent a symmetric and equally open driver on both sides only at the expense of some efficiency.
But who cares when you have HP amps capable of delivering several Watts.

That could very well be right! Very intriguing. Also somewhere on the head-fi thread someone gave a translation talking about high z drivers and their benefits. I'm wondering if this HE-100 is using some of the same tech as the prototype high z audeze.

Asymmetrical dual-sided magnet planar is what I'm seeing from the presentation... like Solderdude said: one side with bigger (more powerful) magnets, and the other with smaller (less powerful) magnets.

My guess is that they're learning from the HE-560 and HE-400i that one-sided magnet can cause bass to have less control because at high amplitude excursions (especially at low frequencies), the diaphragm would get further and further away from the magnetic field gradient, and then the strength of the magnetic field would not be enough to "stop" the diaphragm in time. This is the same problem with the Abyss, and why the Abyss would have "more bass" when the seal is broken, whereas it's simply... just uncontrolled in that case.

Either way, yeah, I concur. It seems like a good idea. Smaller magnets on ear side = less multiple-slit diffraction = less weird waveform than symmetrical dual-sided = more pressure to ear side = as much bass as single-sided but with more control.

I hope the smaller magnets on ear side provide benefits for more than just low bass as well. Rattling or uncontrolled low bass was never an issue for me with the 560. Particularly, I'd like to see smoother response in the low-treble area which both the 400i and 560 suffer a little bit from.

It doesn't matter anyways, looks as though I won't be able to afford this new headphone-- unobtanium status. (Nor would I be caught having such a gaudy piece of kit on my desk.)

Well, depending on how it's arranged (probably just another alternating bar magnet pattern, though I could be wrong), I think it'll have acoustical benefits beyond that.

I think the low-treble issue of the 400i and 560 are more from reflections caused in the back of the driver baffle, especially with the stock grill. Swapping for a different grill (or just go complete open) helps somewhat. I put a piece of sheet liner directly on the back of the driver baffle and it seems to help with the rest. Wonder how the new cup shape will help... aside from looking gaudy.

God, that's one headphone I probably won't own even if I had the cash to purchase it.

One maybe one-sided magnet has better bass control, i.e. Abyss, HE-400 (old one).

Bill-p · « **Reply #28 on:** December 30, 2014, 10:50:38 PM »

Yeah, I'm thinking that as well.

Strong magnets in the back -> strong push force towards ears.

Weak magnets in the front -> just enough stopping force to keep bass tight and diaphragm in control

Now I'd imagine reverting the phase of the signal on this headphone won't be fun...

Are they using an array of small magnets or a single one with holes cut into it?
